To all-whom it may concern.' i

Be it known that I, ALEXANDER Lnvnfrr, a citizen of the United States, and a resident of the city of New York, borough of Manhattan, in the county and State of New York, have invented a new and Im roved Builing or Polishin Wheel of which the following is a full, c ear, and exact description.

The invention relates to bulnlg or elishin wheels made of cotton, woo leatV er or ot er material, andl its object is to rovide a new and improved builin or polishing wheel arranged to prevent the oss of the material of which the wheel is made and to ermit of using thewheel until the materia is worn away, practically down to the hub or center piece. Another object is to provide a buing or polishin wheel which is exceedingly stron and urable and which can be cheaply an quickly manufactured with a minimum amount o material.

With these and other objects in view the invention consists of certain novel features cfm-instruction as hereinafter shown and described and then specifically pointed out in the claims. i

A practical embodiment of the invention .is re resented in the accompan g drawin ormin a art of this ecication, in wlisch similgr characters of siPeference indicate co 'r ondin parts in all the views.

extended position andrior to be-4 In the manufacture of buiiing or polishing wheelsof woven fabric strips as hereto ore practised, it bias been customary to superimpose such strips and to fasten the same together by stitches a distance from the marginal edge of a strip.' Now as the wheel wears down to the row of stitches the remaining mar nal portion of the strip becomes Vdetache and flies oil'I the rotating wheel by the centrifugal force and hence such material is not utilized for builing ,or polishing purposes and is lost. In m invention presently to be described in etail the stri of material is `doubled uprwidthwise an athered along the doubled up or median e ge, and this strip is wound on the hub or center of, the wheel to permit of using the strip up to the gathered edge, that is, to the centeror hub of the wheel, and very little material is lost.

In its simplest form, a strip 10 of cloth or other suitable material is doubled up widthwise to provide a median line or edge 11 and members 12 and 13, the'outer ed"es of. which form the peripheral face of he wheel. The gathered'. edge 11 is. wound around a core or disk 14. By the arrangement described a unit is formed and any number of such units may be placed l togather, one alongside the other as Shown in Fi 2, for ma g a-builin .or polishing whee of a desired width. e o osite faces of the body are covered by di s 15 connected with each other by rivets, bolts or other suitable fastening means' 16, not necessarily extending throih the material of which the body is form In practice,

the strip 10 is held in doubled up and gathered osition around the core 14 in a number o l.superimposed layers by the use of-a stri v 20 tied around the outermost layer, `as plai y indicated iii Figs. 6, 7 and 8. In practice, the unit is formed onfan apparatus such as shown and described in 'my ap lication for Letters Patent of the United tetes, No. 233,757, filed by me on May 10, 1918. In the apparatus shown in Fig.l 8 the ocre 14 4is has bawntwo disks 21 w21 sai-wiel an axle 23 extending centrally through the 105 core and held in the disks 21, 22. The inaterial is wound around the disks 20 and 21 once or a number of times and with. the middle of the material at the groove formed between the disks. The string or cord 20 is now placed around the material o posite the groove and drawn ti ght to draw tige material a ers to form the members 12 .preferabl built up of -a number of superimposed isks of pasteboard or like material according .to the thickness of theunit bod formed by the'members 12 and 18 and whic latter correspond each to the number of windi y y given the material around the disksgIsand 22. The strip 10 is preferably cut bias fashion from a iece of material so that the outer edges of t e members 12 and 13 do not ravel thus insuring the proper use of the buiiing or polishing Iwheel without an waste of material.

n order to give more fullness to the bufiing or olishing wheel, the main strip 10 is provi ed with two intermediate strips of material 25 each doubled uplwidthwise to rovide a median line or edge 26 and meiners 27 and 28. The strips 25 are fastened a-lon their median lines 26 by stitches 29 to t e members 12 and 13 of the main or carrying the strip 10 and at a point a distance from the median line 11 of the main or carrying strip 10. To the member 27 of each intermediate strip 25 is secured an outer doubled u'p strip 30 of material similar to that of which the main strip 10 and the intermediate strips 25 are made, and this outer strip has a median line 31 and two members 32 and 33. Eiwh strip 30 is fastened along its median line 31 by stitches 34 to the member 27 of the corresponding intermediate strip 25 a distance intermediate the outer and inner ed es of the said meinber 27, as will be readi y understood by reference to Figs. 1, 3, 4, 5 andr6. The outer edges of the several members' 12, 13, 27 28, 32 and 33 are disposed in the same p ane and form the erilpheral edge of the buiiing or polishing w ee It will be noticed that the main or ca ing strip 10 is wider than the strips 25 an the strips 30, and the stri s 25 and 80 are arranged between the mem rs 12 and 13 of the outer or carrying strip 10. By the arrangement descri ed a body is formed of a series of strips providin superimposed layers, each strip bein dou led up widthwise'along the median ine of the strip thus providing each strip with two members of practical y equal width.

The main strip. 10 is further provided with a iillin` strip 40 double'dup' widthwise and fastene aloii its median line 41 by y stitches 42 to the oubled up edge 11 of the main or carrying strip 1j0, as plainly shown in Figs. 1,l 3, 4, 5 and 6. This doubled u filling strip 40 provides two members 43 an 44, the outer edges of which terminate adjacent the median lines 26 of the intermediate strips 25.

the latter are wider than' l ,BDIJIS In practice, the strips 10, 25, 80 and 40 are sew together in o en width, as plainly shown in Fig. 3, and t e median line 11 of the main or car ing strip 10 is thered either by the stitc es 42 or by the insertion of a cord or string 20 at the median line 41.

AIt will. benoticed that when the buiiing or polishing wheel is in use and its periph e a edge is gradually worn down until the stitches 84 are reached then the outer strips 30 have been com letely used without any loss of material. hen the wheel is further worn down to the stitches 29 then the strips 25 .have been used up without loss of material and the wheel can be practically worn down to the hub or center o the wheel.

It will further be noticed that by doubling up the strips and fastening the same together a on the median line an exceedingly large num er of layers of material are provided in the body 10 of the wheel.

It is understood that in each unit the strip is wound around the hub or center at least once but in practice the strip is wound around a number of times to form superimposed layers doubled up widthwise and gathered at .the doubled u edge, as above explained and illustrated 1n the drawings.

t is further understood that I do not limit myself to any particular material of which th'e stri s are made, as cotton, wool, or other materia may be used.

Itis further understood that I do not limit myself to the number of doubled up auxiliary strips of fabric material shown and described, as the same may be increased or entirely eliminated without deviating from the spiritof my invention.

Having thus described my invention, I
